Multisim freezes when using external hex file compiled using CCS C, PIC C Compiler

[TheDestroyer]

Guys, Please help I need Immidiate help with this problem!!

I'm learning now how to program PIC16F84, And found already a book to teach me CCS C,

I want to apply those projects on multisim, so the only way is to use the hex file with multisim, Because Multisim C language is very different than the CCS C Language

In Multisim, After I select the hex file I programmed, If the MCLR pin was connected to ground the simulation starts without results for of course, but If I connected MCLR pin to VDD, MULTISIM COMPLETELY FREEZES, And never work until I shut it down through windows, and so lose everything and nothing works

Please tell me if there is any modification should be made on PIC C project to make it compatible with multisim, Or if there is another compiler which is already tested on multisim using CCS C language

Thanks

I know from working with the PIC Chip and how the config is set up you can either use a 10K pull up resistor or none at all. I would try adding the 10K resistor from MCLR to the supply voltage and see if that helps.

I have same problem. Any new solutions?

I'm sure the code is OK, I'm using pull up resistor on MCLR, maybe there could be a problem with oscilator type?
